I just finished wiring a Ross 4-way turnout using a DZ1000 motor. First was to connect power and make sure the switch was working properly. Second was adding the non-derail feature. This W/E I added the DZ1011R signal detector in conjunction with a DZ1008 relay to indicate turnout position. The attached diagram is for one section only. You will need three pairs of DZ1011 / 1008 for the 4-way.
